//! Describes a line in 3D space. <br>
//! A line is positioned in space with an axis (a gp_Ax1 <br>
//! object) which gives it an origin and a unit vector. <br>
//! A line and an axis are similar objects, thus, we can <br>
//! convert one into the other. A line provides direct access <br>
//! to the majority of the edit and query functions available <br>
//! on its positioning axis. In addition, however, a line has <br>
//! specific functions for computing distances and positions. <br>
//! See Also <br>
//! gce_MakeLin which provides functions for more complex <br>
//! line constructions <br>
//! Geom_Line which provides additional functions for <br>
//! constructing lines and works, in particular, with the <br>
//! parametric equations of lines <br>
